TAKE-UP.'

Application led May 1, 1924. Serial No. 710,437.

This invention relates to improvements of the guides and their original supporting in take-up devices for the guides of locomeans. f Y motive cross heads and has as its object t0 The means provided for effecting adjust- 55 provide means whereby the said guides may ment of the rear ends of the guides 2 is iden-v Y 5 be adjusted with relation to each other so tical in the instance of each of the guides as to compensate for wear of the guides and except that the means for adjusting the upcross head and thus prevent pounding. per guide is arranged above the said guide Another object of the invention is to proand between the upper side of the said guide 60 vide a take-up which may be readily and and the lugs 6 of the yoke 5, whereas the 10 quickly adjustedrwithout the necessity for means for adjusting the lower guides is disassembling any of the parts and by admounted beneath the said guide and between justing which the precise degree of adjustthe under side thereofl and the correspondment of the guides to take up the play of the ing lugs 6 of the yoke 5. The adjusting 05 cross head may be effected. means comprises a shim member 8 having a In the accompanying drawings: head 9 and a tongue 10 which extends sub- Figure 1 is a side elevation, parts being stantially at right angles from the lower side shown in section, illustrating the device emof the said head 9. The tongue 10 is of bodying the present invention installed, wedge-shape and is decreased in thickness 70 Figure 2 is a perspective view of one of the gradually from its juncture with the headV 2U wedge shims constituting a part of the de- 9 to its freev end and said tongue is formed vice, l with a longitudinally extending slot l1 Figure 3 isa vertical transverse sectional which opens through the said head thereofA view taken substantially on the line 8 3 of An opening 12 is formed in the head Qand 75 Figure 1, looking in the direction indicated accommodates one end of a threaded rod 95 by the arrows, 13 which is secured at its other end by means Figure. 4 is a view similar to Figure 3, of nuts 14, in an opening in the yoke 5. illustrating a modified form of the invention. The tongue l0 of the'shim is fitted at its In the drawings, the numeral 1 indicates free end portion between the respective guide l the cylinder head of the locomotive and 2 and the respective lug 6, and the slot 11 2 the usual guides which are ordinarily anreceives the bolt 7 so that there is no interchored by bolts 3 to the usual Vlugs 4 upon ference offered to the longitudinal adjustthe cylinder head and extend from the cylment of the shim member and likewise, latin der head to the usual yoke 5 by which their eral displacement of the said member is ends remote from the cylinder head are supprevented. Nuts 15 are threaded onto the ported. Ordinarily, the yoke 5 is provided end of the rod 13 which extends through with outstanding bosses or lugs 6 to which the opening 12 and may be adjusted so as to the guides 2 are secured by bolts 7. This Veffect longitudinal adjustment of the said manner of mounting the guides 2, however,- shim member. As before stated, ythe shim 00 does not provide for any compensation for members 8 are arranged respectively above wear of the guides and cross head working and below the upper and lower guides 2 and therebetween and, therefore, the present inbetween said guides and the respective lugs vention contemplates the. provision of a sim- 6, and it will be evident, therefore, that by ple andV eflicient means whereby the guides adjusting the members in the direction of 95 may be adjusted toward each other, while the yoke, to a greater or less distance, the maintaining parallelism, so as to take up the tongues 10 of the shims will, due to their wear between the parts and eliminate poundtapered or wedge-shaped formation, cause f ing. y lowering of the rear end of the. upper Substantially the same mechanisms are guide 2 and elevation of the rear end of 100 providedV at the front and rear ends of the the `lower guide 2.. guides 2 for adjusting said guides except The means provided for effecting asimilar such slight modifications as are necessary adjustment of the forward ends of the guides to conform to the positions and arrangement 2 is clearly shown 1n Figure 3 of the drawings, in which figure, the numeral 16 'indicates a bracket plate which is secured at one end to the under side of the lower guide 2 and upper side of the upper guide 2. Except for this relative reversal of the parts, the two adjusting devices for the said forward ends of the guides 2 are identical. The bracket plate 16 is provided with a right angularly turned end 17 having an opening formed therein, and a bolt rod 19 is slidably fitted through this opening and nuts 2O are threaded onto the said rod and may be adjusted to adjust the rod and are located at opposite sides of the upturned end 17 of the bracket plate so that after the adjustment is effected, both nuts may be tightened to prevent any displacement of the said bolt rod 19. The other end of the bolt rod fits through an opening 21 formed in the head 22 of a shim member 23 which corresponds substantially to the shim member 8 previously described and which member further includes a tongue 24 extending` at right angles from the head 22 and provided with a slot 25 to accommodate the bolt 3 of the respective guides 2. yThe shim tongue 24 extends between the respective guide 2 and the respective lug 4, and the end of the head 22 rests slidably against the face of the bracket plate 16, nuts 26 being threaded onto the bolt rod 19 and bearing at opposite sides of said head 22 of the shim member. By reference to Figure 1 of the drawings, it will be seen that whereas the tongues of the shim members 8 extend longitudinally of the guides 2, the tongues 24 of the shim members 23 extend transversely of said guides. Likewise, it will be observed that in the instance of the members 8, the bolts 7;,are to be loosened and the members S then adjusted in the direction of the yoke 5, to properly lower or elevate the rear ends of the upper and lower guides respectively, after which the bolts are to be tightened to maintain the adjustment, whereas in the case of the shim members 2 3, the members are to be adjusted in a direction away from the forward ends of the Iguides 2 or, in other words, are to be partly withdrawn from between the said ends of the said guides and the lugs 4, in order to permit of a suitable lowering of the forward end of the upper guide and an elevation of the forward end of the lower guide.

In that form of the invention shown in Figure 4 of the drawings, the structure is substantially the same as that shown in Figure 8, except that in this instance, the head of the shim member, which member is indicated by the numeral 2T, is omitted, and a threaded stem 28 extenos directly from the major or thicker end of the shim member and is adjustably secured to the opening in necessary to provide, in the shim members 8 and 16, more than one of the slots 11 and 25, respectively, and therefore the invention is not limited to the illustrated number of such slots nor to any particular proportioning of the shim members or other parts of the take up.

Having thus describedthe invention what 1 claim is:

1. A structure of the character described comprising guide bars spaced transversely from each other, a support extending in crossed relation to said guide bars adjacent one end thereof, rigid lugs extending fromV said support adjacent the outer faces of said guide bars, stationary supporting lugs extending between the opposite ends of said guides from said support and adjacent their inner faces, securing bolts passed through alined openings in said Alugs and guide bars, tapered wedges fitted between said guide bars and the first-mentioned lugs andv extending longitudinally of said guide bars, tapered wedges fitted between said guide bars and the second-mentioned wedges and extending` transversely of the guidebars, and means to adjustsaid wedges and releasably secure the. same in set positions to retain the guide bars parallel and in predetermined spaced relation to each other.

2. A structure of the characterdescribed comprising guide` bars spaced transversely from each other, a supporting bar extend? ing in crossed relation to said guide bars, rigid lugs extending from said supporting har longitudinally of the outer faces of said guide bars, securing bolts passed through said lugs and guide bars, tapered wedges extending longitudinally between said lugs and guide bars and provided with arms extending transversely from the guide bars in spaced relation to the ends of said lugs, threaded rods passed through alined openings in the supporting bar and arm, securing nuts screwed upon said rods and adapted to firmly grip opposed faces of the supporting bar and arm and securely hold the rods in place and releasably secure the wedges in set positions, supporting lugs extending` longitudinally of the inner faces of said guide bars at the opposite ends thereof from said supporting bar, bolts extending through said guide bars and last-mentioned lugs, wedges extending transversely of said guide bars and fittedV between the guide bars and last-mentioned lugs, and means to adjust the last-mentioned wedges and retain the. same in set positions.

3. A structure of the character described comprising a guide bar, a stationary supporting lug extending above and longitudinally of said guide bar at one end thereof, a securing bolt passed vertically through said lug and bar, a bracket Carried by said bolt and extending across the under face of said guide bar and projecting from one sideV thereof and provided with a side arm eX- tending upwardly in spaced relation to the side of the guide bar, a wedge passed transversely between the lug and guide bar and provided with av depending side arm extending towards said bracket between the guide bar and arm of the bracket, a threaded rod extending through alined openings in the arms of said wedge and bracket, and securing nuts screwed upon said rod and adapted to grip opposed faces of the arms and releasably secure. the wedge in set positions.
